If you want to add those, add the hours and the minutes separately. Then, if you have 60 or more minutes, convert that to hours and minutes - remembering that there are 60 minutes in an hour.
Just multiply the number of hours by 60, then add to the minutes.
take away the minutes and convert the hours to minutes 1h=60min when you are done add the original minutes back
3 hours is 180 minutes so add 30+180=210 minutes.
They add up to 150 minutes
One hour = 60 minutes, so 3 hours = 180 minutes. Add the 30 minutes, and you get 210 minutes.
Just convert the hours to minutes (1 hour = 60 minutes), then add everything.
If you want to convert it to hours, divide the minutes by 60, and add to the hours.
2.5 hours is in 147 minutes the way u get that is add 60 and 60 to get 120 then you get 2.5 hours
Break it down into hours and minutes... 2 hours plus 2 hours is (obviously) 4 hours. Now... 0.5 of an hour is 30 minutes, so you need 2 x 30 minutes (1 hour). Add that to the original 4 hours = 5 hours in total.
Well 3 hours is 180 minutes,so you add 7 and it will be 3hours and 7mintues
-- The 48 minutes are already in minutes, so set them aside while you work on the 6 hours.-- 1 hour = 60 minutes. 2 hours = 120 minutes. 3 hours = 180 minutes. 6 hours = 360 minutes.-- Go get the 48 minutes, add them to the 360 minutes, get 408 minutes all together.
